The WDT is now "standard operating procedure" at my place.
I must have been looking at same site Greg. being fairly new still to the CS scene, I gave it a go and was impressed also. My tool is a small thin cake tester that my Mother in Law used to have years ago, and being the sentimental type I never wanted to throw it out cos it had a cute top/handle on it! it is much thinner than the usual cake testers. as to the funnel used... I cut the botom off a small tupperware container and its pretty useless actually! :-/ will have to do some more lateral thinking as to what I may use for that :-?
